Problems solved by technology
[0005] The problem solved by the present invention is that the mechanical arm of carbon fiber material or carbon fiber composite material and the supporting part are screwed together with screws, and the screw loosening phenomenon is easy to occur during use, so that the operation accuracy of the mechanical arm is reduced, the work efficiency is low, and even the equipment may be damaged. Problems with failure or downtime

Embodiment Construction
[0026] Please refer to figure 1 , the inventor found and analyzed that the reason for the lowered operation accuracy of the mechanical arm 12 and the low working efficiency of the mechanical arm 12 is that the mechanical arm 12 and the support member 11 are screwed together with screws 13 . The screw 13 is screwed into the screw hole 15 through the through hole 14, the surface of the through hole 14 has no thread, and the screw hole 15 is a blind hole (one end of the blind hole is blocked), and the thread in the screw hole 15 is mainly used for Clamp screw 13 under tension. The rotational force or torque applied to the thread of the screw hole 15 will stretch the screw 13 , generate tension, and then generate a clamping load to fix the screw 13 to the screw hole 15 . However, as the mechanical arm 12 is constantly carrying out load-bearing operations, the mechanical arm will bend and vibrate, and a small gap 16 will appear between the screw 13 and the screw hole 15, so that t...

The invention relates to an assembling method of mechanical parts. The assembling method includes providing a first mechanical part made of carbon fiber materials or carbon fiber composites and provided with screw holes and providing a second mechanical part provided with through holes; coating glue at the bottom of screws; passing the screws after being glued through the screw holes and screwing the screws into the screw holes until the screw holes stop moving; standing still after the screw holes stop moving until glue solidifies into membrane to form a gel layer. With the assembling method of the mechanical parts, assembling strength of the screws and the screw holes is increased, screw loosening condition during load-bearing operation of mechanical arms is avoided, operating accuracy and working efficiency of the mechanical arms are improved, equipment failure or shutdown is avoided and operation is simple and convenient.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for assembling mechanical components. Background technique [0002] Robot (Robot) is a precision mechanical device that performs work automatically. It is the product of advanced integrated cybernetics, mechatronics, computers, materials and bionics. It has important uses in fields such as industry, medicine, agriculture, construction and even military affairs. Industrial robots can be proficient in cutting, grinding, welding and warehouse handling, and the main working parts are mechanical arms. At present, this kind of robot is made of carbon fiber or carbon fiber composite material, which overcomes the shortcomings of heavy weight, poor mechanical properties such as rigidity and strength, low flexibility, high cost, and large investment. [0003] For example, in the Chinese patent literature with the publication number CN102407524A (publication date: April 11, 2...
